That would be incorrect, since it messes up the LOD adjustment. The 1024x1024 level 15 tiles should be split into 512x512 tiles and added at level 16. After that, the level 14 and level 15 tiles should be interpolated down to 512x512.

Indeed the Ascension tiles are all 512 * 512

Edit:
Wehaveaproblem it reported that some tiles are more than 512 * 512, I have taken action to correct.

No ! I was based on the location of the Papyref and mustard's buildings, and I adapted my textures.
I realized during my preliminary studies with Orbiter in 2016 that the localisation of kourou was wrong: too close to Cayenne ... This will be fixed for the 2016 version ... So this take me more time... ..

By the time I took knowledge of the structure of the orbiter tile in the 2016 release, I 'd, among others, looked at the situation of a few bases, including Kourou - with the intention to see if it was interesting to create a night texture for them - and that, surftilecalculator "in hands" and the corrected Martin's formulas under the eyes. That is what I had been surprised by the position of Kourou in Orbiter in 2010 with respect to real coordinates. I actually thought this would be due to an incorrect positioning of meshe that supports all of Kourou. Too south at least, if memory serves.

Otherwise, more generally, as you can probably think it now, as regards the tiling in version 2016, compared to 2010, nothing really new under the sun, and making a base - except the issue of elevation - in the latest version, is not more difficult than in the 2010's one

J' avais été étonné de la position de Kourou dans Orbiter 2010 (...) Trop au sud, à minima, si ma mémoire est bonne.

On the command line every character matters. These 2 (linux) commands have 1 character difference, but one removes a directory in the root directory called 'tmp', the other removes every file and folder on the entire system. (if logged in as root)
